(62 Hillside Ave, Smyrna, Ga.) Continuation of application Ser. No. 184,910, Mar. 27, 1962. This application Mar. 12, 1963, Ser. No. 264,521 1 Claim. (Cl. 254139.1)

This is a continuation of my coapending application Serial No. 184,910, filed March 27, 1962, and now abandoned.

This invention relates to a toy lifting device for a childs vehicle and particularly to a toy derrick or hoist which may be attached to the rear of a childs tricycle and having an operating means thereon which maybe used by the child in play to lift or lower various articles.

A child riding his tricycle or similar vehicle enjoys simulating things which he has seen adults perform with actual equipment, such as imitating motorcycle policemen, ambulances, or various other acts and people that he has observed. It has beend found entertaining for the child to imitate the pulling or towing of various items by the use of a rope or string and even more entertaining to have a lifting device such as a hoist or derrick present on the vehicle. The instant invention provides a toy lifting device or hoist which is attached to the rear of the tricycle or similar childs vehicle so that it may be manipulated and used by the child at play.

Generally described, the present invention comprises a boom or hoist main member protruding outwardly from the rear of a childs tricycle or similar vehicle and being supported on a pair of diagonal support arms constructed from tubular pipe or similar material flattened at the ends and bolted together on opposite sides of the boom intermediate its length. The bottom 'of the respective diagonal supports are flattened and bent outwardly and provided with openings through which bolts are inserted to connect the respective supports to the rear foot tread plate of the tricycle or similar vehicle. One end of the boom is provided with a collar or Ushaped attachment member having a plurality of spaced and matching holes through which is inserted a bolt to attach the boom to the frame of the tricycle behind the seat. The outward or terminal end of the boom is provided with a bracket or holder on which is mounted a movable pulley receiving a hoist rope or string attached at its inner operating end to the winding spool or drum held in a bracket fas tened to the top of the boom. The bracket supporting the winding drum is provided with a shaft and crank handle on which is attached a ratchet member engageable by a pivoted pawl attached to the boom. The hoist rope has a conventional S-hook attached thereto. In operation, a child can maneuver the tricycle and vehicle in any manner he sees fit playing-like he is a wrecker or lift truck vehicle lifting an item such as a wagon or other article through the attachment of the shock in place and the cranking of the crank handle which latches in place each inclement as the pawl is engaged in the ratchet. To lower the device, the child merely relieves the pressure of the pawl and the ratchet by hand and allows the device to lower to the ground.

An object of this invention is to provide a toy lifting or hoisting device fora childs vehicle.

A further object of this invention is to provide a simple toy device which can be constructed from three pieces of tubular pipe or similar material held in place by conventional screws and having a simplified rope hoist arrangement thereon.

A further object of this invention is to provide a childs play hoist device which may be attached to the frame of a tricycle through the use of only a few screws and which has easy manipulation by the child.

"ice

Other and further objects and advantages of my invention will become apparent upon reading the following specification taken in conjunction with the accompanying drawings, in which:

FIG. 1 is a side elevation view of a conventional childs tricycle with the hoist or lifting device of the present invention mounted thereon and having partially lifted a toy wagon.

FIG. 2 is a perspective view of the lifting device shown on the tricycle in FIG. 1.

Referring initially to FIG. 1 and then to the other figure of the drawing, a conventional childs tricycle 10 is provided with the usual seat 12 adjustably held on a seat support rod 14 on a curved frame member 16 attached at the lower bottom to a flat, horizontal foot tread plate 18 supporting a shaft on which are mounted the pair of opposed tricycle rear wheels 20.

The lifting device of the present invention is designated generally by the reference numeral 24 and consists of a tubular boom or main lifting member 26 constructed from tubular aluminum, steel or similar material of preferred lightweight construction and economical cost. Boom 26 has on one end thereof a collar or U-shaped attachment member 28 which is provided withopposed pairs of matching and aligned and spaced attachment holes 30 in which may be inserted an attachment bolt 32 held in place by a conventional nut 34.

The boom 26 has on the outer, terminal end thereof a pulley bracket 38 comprising a base portion 40 curved on the underside and welded or otherwise secured to the metal boom 26 and ,a pair of spaced pulley plates 42 supporting a pulley 44 on a shaft 46. Near the rear of the boom 26 there is another pulley bracket 50 with opposed plates 52, attached by welding or otherwise secured to the top of the boom 26, and having a shaft portion 54 of a crank member 56 therethrough supporting a wind-up drum or pulley member 58 on which the rope 60 is wound. Crank 56 is provided with a ratchet member 62 engageable by a pivoted pawl 64 mounted on the side of the boom 26.

The boom 26 is readily and easily atached to and detached from the tricycle by means of the collar member or U-shaped member 28 and bolt 32 previously described and also supported on a pair of diagonal support members 68 of substantially identical construction each having :a flattened upper end 70 and a flattened outwardly extending lower end 72. Ends 70, 72 are provided with openings 76 therein to receive at ends 70 .a bolt 78 passed through the boom 26 and held in place by a conventional nut 80. Each of the outwardly extending flattened portions 72 are fastened in place in spaced relation on the tread plate 18 by boring or drilling holes therein and inserting an attachment nut and bolt arrangement 84 therein.

The operation of the device is believed to be fairly well apparent from the above noted description. With the diagonal member 66 bolted in place by bolts 84 on the tread plate 18 and with 'the U-shaped member 28 bolted in place by bolt 32, the lifting device is in stable attachment on the tricycle and capable of being used by means of an S-hook tied to the end of rope 60 and inserted on an edge or lip of any device such as the toy wagon 92 shown in FIG. 1. Cranking of the crank member 56 in one direction slides the pawl '64 over the ratchet 62 and allows the rope 60 to wind on the drum or pulley 58 to wind up the rope 60 and lift the toy device 92 or other device being lifted. Conversely, when the child desires to drop or lower the lifted item, he merely reaches around and lifts the pawl 64 sufii-ciently to permit the pawl 64 to disengage from the ratchet '62 and the weight of the item being lifted 92 or other item plus the weight of the S-hook 90 will cause the rope to unwind and the end to drop to the ground.

While I have shown and described a particular embodiment of my invention, together with a suggested mode of operation thereof and the attachment to a particular vehicle such as a tricycle, it will be apparent to those skilled in the art :that other childs vehicles may be used and that various substitutions, eliminations, deviations, changes, andramifications may be made in the embodiment shown and described without departing from the scope thereof as defined in the appended claim.
